The tax break most Americans abroad rely on can quietly zero out their IRA for the year
Here’s a wrinkle in the tax code that catches even careful planners off guard: you can earn a totally normal salary while living abroad, claim the exact tax break every expat guide tells you to claim, and still end the year with zero room left in your IRA. Not reduced — zero, even if your bank account tells a very different story. It’s a legal, well-documented quirk of the Foreign Earned Income Exclusion, and almost nobody mentions it until it’s already too late to fix for that tax year.
The IRS doesn’t hide this rule, but it’s buried deep enough in Publication 590-A that most people never go looking for it. Here’s what’s actually going on, and the one workaround that can undo it — for a price.
What “excluding” your income actually costs you
The Foreign Earned Income Exclusion (FEIE) lets Americans living and working abroad shield up to $132,900 of foreign earned income from US tax in 2026. It’s genuinely one of the better perks of expat life, and most people are right to claim it. But the IRS is explicit that any income you exclude from your taxes — foreign earned income included — does not count as compensation for the purpose of contributing to a Traditional or Roth IRA.
Compensation is the entire basis for IRA eligibility. Sounds like a technicality? It’s not — it’s an all-or-nothing switch: no compensation on paper means no contribution room, full stop, no matter how much you actually earned or how healthy your bank balance looks.
The math that actually plays out
Say you earn $70,000 working remotely from Lisbon or Chiang Mai and exclude every dollar of it under the FEIE. On paper, your IRA-eligible compensation for the year is exactly $0 — meaning $0 in Roth or Traditional IRA contributions, even though $70,000 landed in your account. Earn more than the $132,900 cap, though, and the math flips: the leftover amount above the exclusion still counts as real, taxable compensation, and you can use it to fund an IRA up to the 2026 limit of $7,500 (or $8,600 if you’re 50 or older).
Most expat tax guides mention the FEIE like it’s an automatic win, and for your tax bill, it usually is. Nobody frames it as a trade-off against your retirement account, though, and that’s the part I think deserves a lot more airtime than it gets.
The spousal IRA workaround that doesn’t always save you
Married couples sometimes assume they can dodge this with a spousal IRA, officially called the Kay Bailey Hutchison Spousal IRA. It lets one spouse fund an IRA for a non-earning partner, as long as they file jointly and have enough combined compensation to cover both contributions.
Here’s the catch: if both spouses excluded all of their income under the FEIE, your joint return shows zero combined compensation too. No compensation, no spousal IRA either — the workaround only works if somebody’s income actually shows up as taxable on the return.
Psst — thinking about actually doing this? I put everything I know about leaving the U.S. for good into one no-fluff guide: visas, jobs, country picks, the works — grab it here.
The one workaround that actually works, and its price tag
There’s a real fix, but it’s not free. Instead of the FEIE, you can claim the Foreign Tax Credit (FTC) on foreign income taxes you’ve already paid. The FTC doesn’t exclude your income at all, so it stays on the books as taxable compensation, which means it counts toward your IRA eligibility again.
So is switching worth it just to unlock a Roth IRA? Here’s the trap: once you revoke the FEIE, the IRS bars you from re-electing it for the next five tax years without approval, and getting that approval means requesting a private letter ruling that costs $3,450 at minimum, and up to $43,700 for higher earners. It’s a real fix, but not a casual one.
If you’re already filing with the FEIE this year, it’s worth a quick check with whoever does your taxes before December 31: are you accidentally locking yourself out of your own IRA? For some people, the tax savings are still worth it. For others, it’s the first they’re hearing the trade-off exists at all.
